Hello,

Just some thoughts to stir the discussion.

There are always too many overloaded words, like "model", but I think 
this does a good job by specifying what representation would be done. 
Plus it aligns well with the WSDM Charter.

Note that the current MOWS Requirements documentation calls for a UML 
representation specifically.  [OVERALL.2].  Perhaps that should be 
included in the definition.

Hmmm.  What about some of the words currently in the MUWS Requirements 
document?

      Specifies how to to use Web services architecture and technology 
to  manage distributed resources, addressing management of any type of 
manageable resource, as long as the resource has a Web Services 
manageability interface, provided by the manageable resource or by 
another entity on behalf of the manageable resource.  Includes defining 
how to represent the manageability interface using WSDL.
      This includes defining:
	-  The components of the manageability interface, including operations, 
attributes, and event notifications.
	-  A core set of manageability interface components, by management 
category (Monitoring, Controlling, Performance, etc.)
	-  Additional sets of manageability interface components that can be 
added as needed
	-  Methods for extending what has been specified
	-  Examples of mapping an existing information model for a managed 
resource to a Web Services manageability interface.
